I believe any deer is a trophy, with any hunting means available, within the laws.
Hunting in NH is much different than my hunting trip to Texas last year or Ala. in 1994, we just don't have those deer numbers up here.
It's more of a question to me about what's more challenging?
Obviously Bow hunting, hunting with a pistol or hunting with a flint lock muzzle loader means you need to have deer closer for an ethical kill within your own abilities.
I use the flint lock as an example against an in-line muzzle loader.
As I can shoot 150 yards with my in-line, plus moisture is not as much of a concern, but probably wouldn't chance a shot over 60-70 yards with the flint lock.
This increases the odds of the deer and the ability of the hunter, along with the famed wind. Luck plays a factor sometimes too!
I am happy with what ever I decide to pull the trigger on, period.
